Knowledge graphs (KGs) are gaining more and more attention nowadays due to their usefulness in many applications. Virtual assistants (VAs) can have a beneficial role in providing a conversational user interface (UI) for KGs. The legal domain touches a crucial aspect of our lives and yet access to legal professionals remains an obstacle. The use of KG-based VAs in the legal domain can help alleviate such a problem, democratizing legal knowledge to anyone, anywhere, and anytime. In this paper, we present our industrial experience in building a VA on top of a legal KG about laws related to labor. We discuss several use cases and lessons learned from what we have done. A demo video to give a glimpse of our KG-based VA is available online at
